NAME

6       sminfo - query InfiniBand SMInfo attribute

SYNOPSIS

9       sminfo [options] sm_lid | sm_dr_path [modifier]
10

DESCRIPTION

12       Optionally  set and display the output of a sminfo query in human read‐
13       able format. The target SM is the one listed in the local port info, or
14       the  SM  specified  by  the  optional SM lid or by the SM direct routed
15       path.
16
17       Note: using sminfo for any purposes other then simple query may be very
18       dangerous, and may result in a malfunction of the target SM.

OPTIONS

21       -s, --state <state> set SM state
22              0 not active
23
24              1 discovering
25
26              2 standby
27
28              3 master
29
30       -p, --priority <priority> set priority (0-15)
31
32       -a, --activity <val> set activity count
33
34   Addressing Flags
35       -D, --Direct     The address specified is a directed route
36
37          Examples:
38             [options] -D [options] "0"          # self port
39             [options] -D [options] "0,1,2,1,4"  # out via port 1, then 2, ...
40
41             (Note the second number in the path specified must match the port being
42             used.  This can be specified using the port selection flag '-P' or the
43             port found through the automatic selection process.)
44
45       -G, --Guid     The address specified is a Port GUID
46
47       -L, --Lid   The address specified is a LID
48
49   Port Selection flags
50       -C, --Ca <ca_name>    use the specified ca_name.
51
52       -P, --Port <ca_port>    use the specified ca_port.
53
54   Local port Selection
55       Multiple  port/Multiple CA support: when no IB device or port is speci‐
56       fied (see the "local umad parameters"  below),  the  libibumad  library
57       selects the port to use by the following criteria:
58
59          1. the first port that is ACTIVE.
60
61          2. if not found, the first port that is UP (physical link up).
62
63          If  a  port  and/or  CA  name  is  specified,  the libibumad library
64          attempts to fulfill the user request, and will fail  if  it  is  not
65          possible.
66
67          For example:
68
69              ibaddr                 # use the first port (criteria #1 above)
70              ibaddr -C mthca1       # pick the best port from "mthca1" only.
71              ibaddr -P 2            # use the second (active/up) port from the first available IB device.
72              ibaddr -C mthca0 -P 2  # use the specified port only.
73
74   Debugging flags
75       -d     raise  the  IB debugging level.  May be used several times (-ddd
76              or -d -d -d).
77
78       -e     show send and receive errors (timeouts and others)
79
80       -h, --help      show the usage message
81
82       -v, --verbose
83              increase the application verbosity level.  May be  used  several
84              times (-vv or -v -v -v)
85
86       -V, --version     show the version info.
87
88   Configuration flags
89       -t,  --timeout  <timeout_ms>  override  the  default  timeout  for  the
90       solicited mads.
91
92       -y, --m_key <key>
93              use the specified M_key for requests. If non-numeric value (like
94              'x') is specified then a value will be prompted for.
95
96       --config, -z  <config_file> Specify alternate config file.
97          Default: /etc/infiniband-diags/ibdiag.conf
